Application July 11, 1944, Serial No. 545,298 Claims. (01. 254-112) This invention relates to improvements in winches.

The principal objects of the invention are directed to the provision of a winch which is adapted for various purposes. It is particularly adapted for use as a stern anchor handling gear on a vessel. It is the practice to beach certain vessels by running the prow onto the beach and the winch apparatus of this invention located on the vessel at the stem is adapted to heave in a line which carries an anchor that has been dropped to the bottom thereby to pull the vessel from off the beach.

The winch of this invention is characterized by means for heaving the line at low speed with a high line pull or at high speed .with a relatively lower ormedium line pull thereby making it possible to exert the necessary effort to free the vessel from the beach and thereafter to rapidly wind up the line. Also with the vessel beached and the line extending from the winch to an anchor astern of the vessel means is provided whereby the line may be kept taut to prevent sidewise movements of the stern of the vessel.

Various novel objects and advantages of the winch of the invention will be hereinafter observed in the accompanying description thereof in the form at present preferred.

Referring now to the drawings in detail, the invention will be fully described.

A frame includes side members 2 and 3 that are secured to and held in spaced relation by transverse members 4, 5 and B. The frame is preferably formed from metal plate and preformed sections secured together by welding.

A platform 1 extends from the rear end of the frame for supporting a.motor 8 which may be of the variable speed reversible type. This motor has a brake drum 9 on its shaft on which a brake shoe or shoes l0 act. These being electrically operated prevent the shaft of the motor from rotating.

A stub shaft ll carried by a bracket l2 secured to the frame side 3 has an anti-friction, selfaligning bearing l3 thereon, see Fig. 5. A shaft ll is mounted by anti-friction bearings 15 and It in a bracket l'I secured to the frame 2 and in clutch part 21. v

A gear l8 fixed on the innerend of shaft I4 is provided with internal teeth IS. A shaft 20 has a coupling 2| fixed on its right hand end which is provided with teeth meshing with the teeth IQ of the gear l8. Said coupling receives an end of the hub of gear l8 as shown. The left-hand end of the shaft 20 has a bull-pinion 2i keyed thereto that is rotatable relative to the stud I I by means of the anti-friction bearing 13. The stud ll, shafts l4 and "constitute what may be called an intermediate shaft. The gear i8 is in mesh with a pinion 22' on the shaft of the motor.

A- quill 24 is mounted in the bearing bracket I1 by means of anti-friction bearings 25 and it has a quill pinion 26 keyed thereto. A clutch member 21 is carried by the outer end of the quill 2| and a clutch member 28 is slidable on the end of shaft I4. Keys or splines bring about rotation of the clutch member 28 by the shaft H. An idler gear 26' is rotatable in bracket If that meshes with pinion 28.

A shaft 30 is rotatable at its left end in a bearing 32 of the frame member 3 and it has a bullgear 34 fixed thereto which meshes with inion 2|. A quill-gear 35 has a hub part 38 associated therewith that is rotatable in a bearing 31 of frame side 2. Said shaft 30 is rotatable in the hub 36 by means of anti-friction bearings 38 3 and it has a sun-gear 39 fixed thereto. 35 is in mesh with idler 26'.

A drum 40 is rotatable on the shaft 30 by means of anti-friction bearings 40'. Studs 44 are carried at one end in the right hand side of the drum and at their opposite ends in a member 45 which is secured to the side of the drum. Pinions 46 on the studs 44 are in mesh with sun-gear 39. A brake drum 4! is carried by a part 48 extending from the hub 36 whereby the gear 35 and brake drum are secured together. Internal teeth 49 carried by the brake drum mesh with pinions 46.

The cable drum 40 is provided with peripherally spaced teeth 50 on its left side and a sprocket 52 is fixed thereto.

The end of a cable is secured to the cable drum and as the cable drum rotates counter-clockwise in Fig. 6 the cable is wound up, otherwise on rotation of the drum in a clockwise direction it pays the cable out.

Means for releasably holding the drum against rotation clockwise for paying out cable include a dog 60 pivoted in a bracket 62, see Fig. 10, that is adapted to engage between the teeth of the Said gear drum. A shaft 6| oscillatable in the frame sides a 2 and 3 has a lever 63 fixed thereto connected by a link 64 to the dog 60. Outside the frame side 2 there is a foot lever 65 that is fixed to the shaft 6I which carries a projection 66, see Fig. 3. A latch 61 is pivoted at 68 to a block 69 fixed to frame part 2 and a rest I is provided for holding the latch in operative position.

As the lever 65 is moved counterclockwise the shaft BI is moved to swing lever 63 thereby to cause link 64 to swing the dog 60 from engagement with the teeth of the cable drum. As the lever 65 is so swung the projection 66 thereof engages the hooked inner end of latch 67 whereby it is swung upwardly so that the said hooked end of the latch engages the projection and holds the lever 65 in the out position of the dog. The lock may be moved to release the lever 65 by pressing on its outer end.

A brake band I4 which may include an outer metallic band lined with suitable material is provided. A bracket I5 is secured to the lower end of the band, see Fig. '7. A spring housing I6 has trunnions TI on opposite sides thereof that are journalled in a plate I8 and a. bearing I9 fixed to the frame side 2. Said housing has two spring chambers such as 80 therein.

Rods such as 6| are carried by a cross-head 82 that is connected to the member of the brake band. Springs 82 around the rods are disposed between the ends of the chambers and abutments 83.at the ends of the rods.

With the brake band 14 frictionally engaging the brake drum the springs 82' resist movement of the brake band in a clockwise direction.

As shown in Fig. 6, the brake band is split at 86 and brackets 81 and 88 are secured to opposite ends thereof. The bracket 88 has worm gears such as 89 rotatable therein by means of antifriction bearings 90. A transverse shaft 92 carries worms 93 that mesh with the gears 89 and rods 94 are in threaded engagement with the said gears.

A shaft 95 rotatable in a bracket 96 extending from the frame side 2 has a hand wheel 91 at one end while its other end is connected by a universal joint 98 to the shaft of a gear 99 in mesh with a gear I00 on shaft 92. The rods 94 are pivotally connected at IOI to the bracket 81.

Accordingly as shaft 95 is rotated in one direction or the other, the gears 69 are rotated to move the rods 94 in one direction or the other. In this way the brake band is adjusted to release the brake drum or it is frictionally engaged, as may be desired.

Means for guiding the cable transversely of the cable drum will now be described with particular reference to Figs. 5 and 11.

Brackets I04 and I05 are carried by the frame sides 2 and 3. Spaced guide rods I01 have opposite ends fixed in the brackets and a shaft I00 has opposite ends rotatable in the bearings I 04 and I05 by means of anti-friction bearings I 09.

A drive shaft IIII below the shaft I08 has its rear end rotatable in the frame side 3 and it has a sprocket III fixed thereto. A chain H2 in engagement with sprocket I I I and the sprocket 52 associated with the drum whereby the shaft I I0 is rotated by said drum.

The forward end of the drive shaft H0 is rotatable in a sleeve II 4 that is rotatable in the bracket I04. A hand wheel H5 is fixed to the outer end of the sleeve H4 and a clutch member H6 is slidable in and out on the outer end of shaft IIO. A key II'I fixed on said shaft IIO prevents rotation of the member |I6 relative to the shaft and a member II8 fixed on the shaft has teeth which are engageable with teeth on member II6. When the member 6 is in clutching position the sleeve H4 is rotated by the shaft IIO. When in an outer position, the sleeve and H0 are disconnected. In this position the sleeve may be rotated by the hand wheel I I 5.

A gear I20 is fixed to the sleeve II4 which meshes with a gear I2I fixed to a gear I22. Said gears I2I and I22 are rotatable on a stud I23 of bracket I04 and the latter gear I22 is in mesh with a gear I 23' fixed to shaft I08. Thus with the member H6 in clutching position the shaft I08 is rotated by the drive shaft I I0.

A carriage I 25 is slidable on the rods I01 and a dog I26 pivoted in the carriage works in a right and left hand spiral groove I21 of shaft I08. As said shaft I08 rotates the carriage is moved back and forth therealong.

'Vertically extending rods I 28 carried by the carriage have rolls I29 thereon and an upper member I30 associated With said rods I28 has arms I 3I between which a roll I32 is journalled. A sheave I33 is journalled at I34 inthe carriage.

A cable is represented by C and it passes between the rolls I29 which cooperate with the sheave I33 to guide the cable onto the drum as the carriage moves back and forth during rotation of the drum.

Means for bearing on the cable to insure that the cable is wound snugly on the drum will now be described with reference to Figs. 5 and 12.

A bracket I40 is secured to the transverse member 4 and it has spaced bearing parts MI in which are disposed opposite ends of a tube I42. The tube I42 surrounds but is out of contact with shaft 20.

Hubs I43 are clamped to the end portions of tube I42 and have upper and lower arms I44 and I45 extending therefrom. Side plates I46 are pivoted at M! to the arms I44 and have rolls I48 rotatable in opposite ends thereof. Transverse members I49 extend between the members I44 to provide therewith a rigid structure.

A spring housing I50 is secured to the frame part 4 and a rod I5I pivoted to the lower end of arm I45 has a spring I52 therearound that is disposed between an abutment I53 thereon and frame part 4. The spring I52 urges the arm I45 clockwise so that arms I44 act on the members I48 thereby to cause rolls I48 to bear on cable on the drum and cause it to be snugly wound thereon.

Means for operating clutch member 28 will now be described with reference to Figs. 1 and 2.

A bracket I68 secured to frame side 2 has up- War ly extending side plates I6I in the upper ends of which a shaft I62 is oscillatable. Levers I83 fixed to the shaft I62 have a ring I64 pivoted in their upper ends which is disposed in a groove I65 01' the clutch member 28. A lever I86 arranged for manual engagement has a depending part I81. A foot treadle I68 is pivoted at I69 and has side parts at opposite sides of part I 61 and a foot engageable member I18. A spring "I has its upper end secured to one of the members IN and its lower end secured to treadle I68 to urge said treadle upwardly against a stop I12.

A switch device I13 is secured to one of the plates IN and it has a movable member I14 engageable by a cam I15 of treadle I68. As the treadle I68 is moved downwardly the part I14 of the switch is actuated. The lever I66 is moved inwardly to engage clutch 28 with clutch 21 and the treadle I68 may be depressed so as to lie below the lower end of lever I61 and hold the lever I81 in clutch engaging position.

The tension control mechanism will now be described with particular reference to Figs. 1, 4 and 6. p

A stand I88 is secured to the frame side 2 whic is tubular in form and carries a cap I8I on its upper side. A shaft I82 rotatable therein has a hand Wheel I83 fixed thereto for rotating the same. Said shaft I82 is threaded and a nut I84 in threaded engagement therewith carries an index I85 that is disposed in a vertical slot I86 so as to be registerable with indicia on the stand.

A link I81 has its upperend pivoted to the block I84 and its lower end pivotally connected to a lever I88 that is fixed to the front end of a transverse shaft I89 joumalled in the frame. A lever- I98 fixed to the rear end of said shaft I89 has a rod I9I pivotally connected thereto at its one end. Said rod I9I has its opposite end pivotally connected to a lever I92 which is fixed to a shaft I93 journalled in frame side 3. A lever I84 is also fixed to shaft I93. A lever having an upper part I95 and a lower part I96 is pivoted to the upper end of lever I94.

A control mechanism I96 is secured to the outerside of frame side 3 and it has a lever I91 fixed to a shaft for operating the same, that is disposed inside of frame side 3. A connecter I98 connects the lever I91 to the lever I95.

Lugs I99 carried by the brake band 14 are connected by a rod 288 to a lever 28I fixed to a shaft 282 rotatable in the frame. A downwardly depending lever 283 is also fixed to shaft 282 and it is connected by the-connector mechanism 284 to the lever I96.

' The member 284 has a rod 285 fixed thereto that is reciprocable in a tube 286, see Fig. 9. The inner end of rod 285 carries a head 281 that is slidable in a lining 288 of the tube 286 and concentrically arranged springs 289 and 2 I8 surrounding the rod 285 are disposed between the head 281 and the stufiingbox construction 2 of the tube 288.

The switch device 2I8 shown in Fig. may be called a dog limit switch and has a lever 2 I5 operable by a cam 2I1 fixed to shaft M. This device is included in circuits and operated in sucha way as to open the circuits so that the drum may not SiI 6 be rotated counterclockwise or in paylng'out direction while dog 88 is holding the drum against rotation.

The switch device I13 of Fig. 2 is also included in circuits, to be described, and has a lever engageable by a part I of lever I61.

The diagram of Fig. 15 will now be described.

Lines of a power supply are shown at 238 and 232. The motor is shown at 8 and the brake drum associated therewith at 9. A brake shoe I8 is held in engagement with the brake 9, as shown, and a solenoid for releasing the brake shoe is shown at 234.

The control mechanism I96 may include resistance members 236 and a swingable arm 238 for traversing the same that is actuated by the lever I 91. Contact bars 248 are also traversed by said arm 236.

Line 232 is connected to the motor by 2144 and to one side of solenoid 234 by 246, A line 248 connects an end of one resistance to the motor. A connection 258 extends between the other resistance and the motor.

Relays 252 and 254 have one side connected to 244 by lines 256 and 258. The movable members of the relays, as shown, are connected to solenoid 234 by 268. The other side of the relays are connected to the bars 248 by 262 and 264. Lines 266 and 288 connect the contacts of relays to power line 238 through 214. The components described constitute the automatic tension control features later to be referred to.

A manual control may include a lever 218 pivoted at 212 and connected to line 238by 214. The

lever 218 is shown in neutralposition and is in contact with a contact 216 that is connected by 218 to 238. Contacts on one side of lever 218 are connected by 288 and 282 to 248 and 264 and contacts on the other side are connected by 286 and 288 to 258 and 282.

In describing the operation of the apparatus it will be assumed that the same is secured to the stern portion of a ship for hauling the ship from the beach after its prow has been beached thereon.

To accomplish this the cable has an anchor fast to its free end. The cable is wound up on the drum and the anchor is let o when the ship is the desired distance from the beach, say sev eral boat lengths.

To drop the anchor the brake band 14 is released by manipulation of hand wheel 91 with the clutch members 21 and 28 disengaged as in Fig. 2 The cable-drum rotates clockwise or in paying-out direction, the anchor bringing up on the bottom.

Slack cable may be taken up by operationof the motor and if necessary prior to releasing the anchor the motor may be operated to raise the anchor from any rest that it may be supported by in order to free the anchor for letting it go.

With the ship on the beach and the line extending from the drum to the anchor the stern of the ship may be moved backand forth by wind or wash so that the ship pivots on its prow. This in some cases is objectionable and is overcome by the tension control mechanism.

The brake band is tightened on the drum by wheel 91 and the motor, of course, is held against rotation by its brake so that movements of the ship put a, strain on the cable. Such a strain tends to rotate the brake drum in paying-out di- 7 brake and brake-band I4. The springs 82, see Fig. 7, are adapted to prevent rotation of the brake-band up to the certain strain on the cable for which they are intended. when the certain strain is exceeded,- however, the brake-band is moved so that through the connections and levers 2M, 2M, 288, I98, I98, I88, I81 (see Fig. 8). the mechanism I98-is operated.

With the ship beached the tension adjusting means is set so that the tension on the cable and the springs 82 are in balance. The members 248 and 238 at one side of movable member 238 of mechanism I98 may be for energizing the motor for paying out rotation of the cable drum while the corresponding elements on the opposite 'side of member 238 are for heaving-in rotation of said motor and cable drum. The central position of member may be called the neutral or of! position.

Assuming the vessel is acted upon by wind or waves to cause it to swing and produce an excessive strain on the line, the brake-band is moved clockwise by the brake so as to operate member 238, through the connections described, and swing it into contact with 238 and 248 for energizing oi the motor in paying out rotation. Thus the drum is operated to pay out cable to relieve the excess strain.

When the excess strain subsides, the ship tends to move back to its original position, due to line tension, and as the force of the springs 82' becomes greater than the line tension so that the brake-band moves counter-clockwise the contact arm 238 contacts 238 and 248 for energizing the motor in heaving-in rotation of the drum so as to recover cable paid out.

That is, when the excess strain subsides so that strain on the cable become normal, contact arm 238 moves to "neutral or "oil!" position. This de-energizes motor and solenoid brake so as to stop the winch and hold the strain.

The manual control may be operated at any time for either paying out or heaving-in cable, and when operated the automatic tension control is cut out.

The automatic tension control may be adjusted by moving member I84 up and down, see Fig. 4. As said member is moved up or down it, through link I81, lever I88, shaft I89. lever I98, rod Ni and levers I82 and I94 shifts the pivotal connection of lever I94 with lever I98 and I98 so that movement of the brake-band operates on lever I91 according to the adjustment. That is, the brake-band may actuate lever I91 and arm 238 so as to produce a greater or less motor torque by moving arm 238 relative thereto in such a way that it cuts out more resistance in the motor circuit for additional torque. Thus the tension control may be adjusted so that when a certain predetermined tension on the cable is exceeded the control mechanism is put into operation for paying out and heaving in'cable.

When the apparatus is to haul the ship from the beach, the cable-drum is rotated in heaving in direction, first at low speed and high line pull and subsequently at a higher speed with lower line pull. To accomplish this the brake-band I4 is disengaged from the brake-drum 41, the motor brake solenoid 234 and the motor 8 are energized, and the clutch members 21 and 28 are engaged.

Under these conditions the sun gear 39, through gears 34, 2|, I8 and 22 connecting it to the motor, is.rotated counterclockwise as shown by the full line arrow in Fig. 14.

Ring-gear 49; carried by the brake-drum 41.

when the brake-band I4 is disengaged from said brake-drum 47. is free to rotate but is connected to the sun-gear 38 through planet-gears 48. Also said ring gear is connected through gears 38, 28', 28 and disengageable clutch members 21 and 28 to the intermediate shaft construction.

The rotation of ring-gear 41 and gear 38 fixed I thereto is limited to a speed less than that of rection or in heaving in direction at low speed and high line pull. Thereby the ship is pulled free of the beach.

When the ship is free of the beach less torque is necessary so that the cable will usually develop slack. It is desired to speed up the heav-.

ing-in operation and prevent fouling of the cable. To accomplish this as stated the apparatus is adapted for operation at high speed.

For high speed operation with the motor brake oil? and the motor operating in heaving-in direction the brake band 14, which has been released from brake drum 4'! for low speed operation, is tightened by manipulation of the band wheel 81 to arrest rotation of the brake drum 41 and thereby the ring-gear 49. The sun-gear 39 driven from the motor through gears 34, 2|, l8 and 22 causes the planet pinions 48 which are rotatable on the cable-drum to roll on or to rotate relative to the now stationary ring-gear 49 thereby to rotate the cable-drum in heaving-in or counterclockwise directions at high speed with lower line pull.

The tightening of the brake band I4 which slows down andultimately stops the brake drum and ring-gear carried thereby so that gear 28 and clutch member 21 come to rest. .As the cable drum accelerates to high speed the clutch-member 28 overrides clutch member 2'! so that it is thrown outwardly by 21 thereby disconnecting pinion 28 from the intermediate shaft.

- When the clutch members 21 and 28 are disengaged as in Fig, 2, the lower end of lever I8'I is disposed within the U-shaped lever I88. To

throw the clutch members into engagement for low speed operation the lever I88 is depressed and lever I88 is moved to the left, whereupon its lower end I81 is disposed over the outer end part of lever I III which is urged upwardly thereagainst by spring I "II.

When the rotation of cable drum accelerates from low to high speed as aforesaid, so as to throw clutch member 28 outwardly and thereby swing the lever I 81' inwardly, the said lever I81 passes from oil lever I88 which is urged upwar by spring "I to the position shown.

It may be noted that with the brake-band disengaged from the brake-drum and the clutch members disengaged that the cable-drum is free for rotation by the pull of the cable while with the cable-drum held stationary the motor and intermediate shaft may be rotated.

The invention may be embodied in other speciflc forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.
